PI. XXVI11, fig. 112. " " 



B. testa ovato-acuta, crassiuscula, dorso laevigata ; basi striata, cinereo- 

 ccerulescente, obscure zonata ; anfractibus prope suturas tuberculatis ; labro 

 postice denticulis muricato, intus striato. 



Shell ovate, inflated, smooth, polished, of a variable color, 

 bluish ash, reddish or brown, covered with narrow, white, 

 longitudinal lines, irregularly spread over it ; a deeper zone 

 surrounds the suture, and two or three others are found upon 

 the lowest whirl , that of the middle much more marked, and 

 sometimes the only one ; spire composed of six convex whirls, 

 slightly flattened at their upper part, and crowned by a row of 

 rounded tubercles ; the three or four upper whirls are folded 

 longitudinally, and intersected by transverse striae. Aperture 

 ovate, notched at the top of the right lip, with a ridge upon 

 the left. The depth of the cavity is brown, and marked with 

 a whitish band. Right lip thin upon the edge, crowned 

 throughout its whole length with small, short, and pointed 

 denticulations, furnished internally with numerous transverse 

 striae ; columella arcuated, covered by the left lip which ex- 

 tends upon the body of the lowest whirl in a white, rather 

 thick callosity, loaded towards the base with some slightly 

 apparent guttules, and terminated by small spinous points. 



Length 14 lines. Width 7 lines. 



Inhabits the seas of Madagascar, and Port Dorey, at New 

 Guinea. 



This shell has some analogy with the preceding ; but several 

 differences distinguish it : it is more elongated ; the last two or 

 three whirls are smooth, and ornamented only around the suture, 

 by tubercles oftentimes rounded ; finally, the callosity upon the 

 body of the lowest whirl is much less prominent.
